Rath R900 B♭/F/G♭/D Bass Trombone

The Rath R900 Bb/F/Gb/D series of bass trombones bridges the gap between student level instruments and our custom, modular, hand crafted instruments. Everything that Michael Rath knows about designing and producing trombones has been utilized in creating a series of trombones that are elegant in their simplicity yet economically attainable.

We’ve taken the most successful modular combinations for the Rath R10, R4F and R9 models and created a range of non-modular instruments - the R100 (Bb medium bore 0.500"), R400 (Bb/F large bore 0.547") and R900 (Bb/F/Gb/D independent valves 0.562").

For those looking to progress from a beginner’s instrument to their first professional level trombone the R00 series of instruments is excellent in developing style and technique before progressing to a fully customized trombone.

On the other hand if you simply want to concentrate on an economic trombone without the potential complications of a modular solution then an instrument from the R00 series would be ideal.

Whatever your needs, the Rath R00 series of trombones offers a unique combination of the highest level of input of design and craftsmanship in trombones with the production qualities that make Michael Rath trombones famous around the world.
